I want to have the nanmean of two matrixes element per element. I don't seem to be able to do it using the function nanmean, since that doesn't sum element per element.

Simplified example:

A= [1 1 1 

    1 1 1

    1 nan 1];



B=[3 3 3

   3 3 3

   3 3 3];

Result I want :

C= [2 2 2

    2 2 2

    2 3 2];

So the nan is ignored.

One way to sum element per element I found on https://nl.mathworks.com/matlabcentral/answers/366304-how-to-sum-up-multiple-matrices-element-by-element

A(:,:,1)=randi([1 3],100,100);

A(:,:,2)=randi([1 3],100,100);

A(:,:,3)=randi([1 3],100,100);

A(:,:,4)=randi([1 3],100,100);

B=zeros(size(A,1),size(A,2));

for i=1:size(A,3)

    B=B+A(1:size(A,1),1:size(A,2),i);

end

disp(B)

BUT this isn't the nansum. How can I do this not taking into account the nans?
